  • Publication number: 20040227413
    Abstract: The invention relates to an electric motor for a linear drive system comprising a motor housing within which a stator, a rotor and a threaded shank are accommodated. The stator has a stator core and phase windings which are connected to phase connectors. The rotor is mounted onto a rotor hub, the rotor hub being supported in the motor housing by roller bearings and coupled to the threaded shank via a thread in order to transform the rotation of the rotor into a translational motion of the threaded shaft. In accordance with a first aspect of the invention, the motor housing has an injection molded part within which the stator, together with the stator core and phase windings, is embedded. A linear guide to accommodate and guide the threaded shank is integrated into the injection molded part of the motor housing.
